Internal Regulations

⚫ "Prevention of Insider Trading and Handling Procedures for Material Internal Information"

When directors, managers, or information recipients of the company actually become aware of material internal information of the company (including information that significantly affects the company's stock price), they shall not, either personally or in the name of another person, buy or sell the company's stock or other equity securities, before or within 18 hours after the information is made public, to avoid those who, due to a lack of understanding of the regulations, inadvertently violate the insider trading red line. The procedures include:


I. Directors, managers, and natural persons designated to perform duties as representatives under Article 27, Paragraph 1 of the Company Act are prohibited from trading their shares during the closed period of thirty days prior to the announcement of the annual financial report and fifteen days prior to the announcement of each quarterly financial report.

II. The General Manager's Office shall, after arranging the agenda for the following year's Board of Directors meeting, clearly inform the regulated parties of the closed period during which they are prohibited from trading shares, in accordance with the preceding paragraph.

III. The dedicated unit established by the Company for handling material internal information and preventing insider trading shall be jointly composed of the Finance Department and the Stock Management Department.

⚫Insider Trading Prevention Education

The Company conducts "Insider Trading Prevention" training on relevant laws and regulations at least once a year for directors, managers, and employees with business-related involvement. In 2025, training materials were provided to current directors, managers, and employees with business-related involvement on July 8, August 18, and September 30, totaling 39 people. The content included common situations where insider stock transactions in listed companies violate the Securities and Exchange Act.


In 2025, the Company notified directors of board meeting dates via email on April 21, July 18, and October 17, and also sent email reminders before the start of the closed period before the announcement of each quarterly financial report to prevent directors from unintentionally violating the regulations.
